What You Need to Know Before Obesity Surgery Obesity surgery is performed not only to achieve weight loss but also to reduce obesity-related health problems and improve quality of life. Proper preparation before surgery directly affects treatment safety and long-term success. 1. Find Out Whether You Are Eligible for Surgery Obesity surgery may generally be considered for people with a body mass index (BMI) of 35 or higher and, in certain circumstances, for patients with a BMI between 30 and 34.9. The decision to undergo surgery should be based on the patient's health condition, existing medical conditions, and specialist recommendations. 2. Choose the Right Surgical Procedure Sleeve gastrectomy, gastric bypass, and other bariatric procedures have different benefits and risks. The most appropriate procedure is determined by considering body weight, diabetes, acid reflux, and other health problems. 3. Complete Preoperative Tests Before surgery, blood tests, cardiac and respiratory assessments, an anesthesia evaluation, and any other necessary examinations are performed. These assessments help identify potential risks. 4. Prepare Your Eating Habits A special preoperative diet may be recommended by the doctor and dietitian. Developing healthy eating habits during this period makes it easier to adapt to life after surgery. 5. Understand the Risks of Surgery Obesity surgery may involve complications such as bleeding, infection, leaks, blood clots, and nutritional deficiencies. You should discuss the benefits, risks, and alternative treatments in detail with your surgeon. 6. Prepare for Life After Surgery Eating habits change after surgery. Small portions, adequate protein intake, vitamin and mineral supplements, and regular checkups become important. Lifestyle changes are necessary for lasting weight management. 7. Choose Your Hospital and Surgeon Carefully Before obesity surgery, research the hospital's facilities, the surgeon's experience, and postoperative follow-up services. Patients traveling to Türkiye for medical tourism should pay particular attention to what the treatment package includes and the follow-up options available after returning home. Conclusion Preparing for obesity surgery with accurate information is the first step toward a safe treatment process. Proper assessment, an experienced surgical team, and preparation for postoperative lifestyle changes form the foundation of long-term success.
